In general, the invention is configured to link a sub-set of data structures out of a global set of data structures based on identifying stimulus type attributes that are structured to produce a functional performance parameter of the associated data structure, particularly in the field of hospital data analysis. Typically, the invention is configured to receive a request for construction of a peer data cluster for a first functional performance parameter of the first entity data structure.

FIELD OF THE INVENTION

The present invention embraces a system, computer program product, and method for data structure clustering based on variation in data attribute performance. The data structure clustering comprises linking a sub-set of data structures out of a global set of data structures in a vector space to form a peer data cluster based on identifying stimulus type attributes that are structured to produce a functional performance parameter of the associated data structure.

BACKGROUND

Database systems typically store vast amounts of data. For various data processing steps, there is a need for determining, selecting and retrieving similar data elements. However, conventional systems merely employ comparative methods to determine similar data elements. For instance, for determining similar hospitals for a particular hospital, conventional systems merely compare properties or attributes of the particular hospital with properties or attributes of all of the other available hospitals in the database. Similar hospitals are typically identified on the basis of matching alone, leading to inadvertently overlooking otherwise similar hospitals that may comprise dissimilar data in the properties or attributes. For example, conventional systems may incorrectly choose a first teaching hospital and second teaching hospital to be similar based on identifying a teaching match, even though the first teaching hospital may be more similar to another large urban hospital. This process needs to be repeated for determining similar data elements for other data elements. As such the repetitive comparisons of conventional systems are time consuming, processing intensive, and possibly inaccurate.

Moreover, in a variety of practical applications the data elements comprise independent attributes that effect dependent attributes. Conventional systems are not capable of distinguishing independent attributes from dependent attributes. Conventional systems, if at all, merely determine similarities based on matching dependent attributes alone, even though the underlying independent attributes causing these dependent attributes may be greatly different. For example, conventional systems may incorrectly determine that two hospitals are similar based on a similarity in the dependent attribute of worked hours per unit, even though the underlying independent variables that result in the worked hours per unit are entirely different, thereby causing a false similarity.

Accordingly, there is a need for an advanced systems that addresses the above technical problems in existing systems. The data structure clustering based on variation in data attribute performance of the present invention ameliorates the foregoing deficiencies of conventional database technology, and also provides several advantages and improvements.

Embodiments of the present invention provide a system, computer program product, and a computer-implemented method for data structure clustering based on variation in data attribute performance.

Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to elements throughout. Where possible, any terms expressed in the singular form herein are meant to also include the plural form and vice versa, unless explicitly stated otherwise. Also, as used herein, the term “a” and/or “an” shall mean “one or more,” even though the phrase “one or more” is also used herein.

In some embodiments, an “entity” as used herein may be any institution employing information technology resources and particularly technology infrastructure configured for storing, analyzing a processing diagnostic and medical databases. Typically, an entity is associated with a variety of features and performance metrics. In some embodiments, an “entity” as used herein may refer to a hospital, and/or a hospital department. That said, the entity may be any institution, group, association, hospital, clinic, medical treatment facility, medical research facility, financial institution, insurance provider, federal entity, establishment, company, union, authority or the like, employing diagnostic and medical data. In some embodiments, “entity” may refer to an individual or an organization that owns, operates and/or is otherwise associated with a system of networked computing devices and/or systems on which the comprehensive data transformation system of the present invention is implemented. The entity may be a business organization, a non-profit organization, a government organization, and the like. In other embodiments, the entity may be a single individual who wishes to perform data structure clustering.

“Computing system”, “computing device,” “server” or “system” as used herein may refer to a networked computing device within the entity system environment or entity system infrastructure (e.g., a system structured for data structure clustering based on variation in data attribute performance, etc.). The computing system may include one or more of a processor, a non-transitory storage medium, a communications device, and a display. The computing system may support user logins and inputs from any combination of similar or disparate devices. Accordingly, in some embodiments, the computing system may be, may comprise or maybe associated with a portable electronic device such as a smartphone, tablet, or laptop, or the computing system may be a stationary unit such as a personal desktop computer, networked terminal, or server. In some embodiments, the computing system may be a local or remote server which is configured to send and/or receive inputs from other computing systems on the network. Furthermore, as used herein the term “user device” or “mobile device” may refer to computing devices such as mobile phones, personal computing devices, tablet computers, wearable devices, and/or any portable electronic device capable of receiving and/or storing data therein.

A “medical diagnostic database,” “diagnostic database,” “first database” or “second database” as used herein, typically refers to a database that is configured to store a plurality of data structures (e.g., having a plurality of functional parameters, and a plurality of attributes), and/or store discrete attribute structures and data clusters constructed by the present invention. The database may be a relational database, a graph structured database, and/or the like.

A “data structure” or an “entity data structure” is a record, node, or other database element which typically comprises or is associated with a plurality of functional parameters, and a plurality of attributes of a particular entity. The entity data structures may include a pointer to one or more data structures, one or more sub-data structures of lower hierarchies (e.g., a plurality of functional parameters, and/or a plurality of attributes of a particular entity), etc. In general, in some embodiments, each data structure comprises a plurality of functional parameters (e.g., performance data of a hospital department entity such as worked hours per unit), and a plurality of attributes (e.g., properties, characteristics and other data related to the hospital department such as patient volume, location, acute care patient days, etc.). This data structure may be directed to describing, recording, identifying and/or documenting characteristics or features of an entity (e.g., hospital or hospital department). Although referred to as “an entity data structure”, it is understood that, in some embodiments each particular entity may be associated with multiple data structures. The data structures, and attributes may comprise descriptive data, textual data, unformatted data, formatted data, or any other available forms of data/information or a combination of forms. This data may be transformed, formatted, encoded, decoded, or otherwise fundamentally altered during storage, retrieval, data/language processing, and other operations.

As described herein, a “user” is an individual associated with an entity. In some embodiments, a “user” may be an employee (e.g., an associate, a physician, a medical practitioner, a project manager, an IT specialist, a manager, an administrator, an internal operations analyst, or the like) of the entity or enterprises affiliated with the entity, capable of operating the systems described herein. In some embodiments, a “user” may be any individual, entity or system who has a relationship with the entity, such as a customer. In other embodiments, a user may be a system performing one or more tasks described herein. “User” as used herein may refer to an individual who may utilize the present invention. The user may be an agent, administrator, or employee of the entity who has authorization to add, modify, or delete data, or query existing data, data structures and/or relationships. In other embodiments, the user may be a client or customer of the entity. In yet other embodiments, the user may be unaffiliated with the entity who has some type of interaction with the entity's system.

As used herein, a “user interface” may be a graphical user interface. Typically, a graphical user interface (GUI) is a type of interface that allows users to interact with electronic devices such as graphical icons and visual indicators such as secondary notation, as opposed to using only text via the command line, such as those associated with the databases. That said, the graphical user interfaces are typically configured for audio, visual and/or textual communication. In some embodiments, the graphical user interface may include both graphical elements and text elements. The graphical user interface is configured to be presented on one or more display devices associated with user devices, entity systems, processing systems and the like. Representations of the constructed data clusters, quality determinations, etc., are typically presented on the user interface.

Database systems typically store vast amounts of data. For various data processing steps, there is a need for determining, selecting and retrieving similar data elements. However, conventional systems merely employ comparative methods to determine similar data elements. For instance, for determining similar hospitals for a particular hospital, conventional systems merely compare properties or attributes of the particular hospital with properties or attributes of all of the other available hospitals in the database. Similar hospitals are typically identified on the basis of matching alone, leading to inadvertently overlooking otherwise similar hospitals that may comprise dissimilar data in the properties or attributes. For example, conventional systems may incorrectly choose a first teaching hospital and second teaching hospital to be similar based on identifying a teaching match, even though the first teaching hospital may be more similar to another large urban hospital. This process needs to be repeated for determining similar data elements for other data elements. As such the repetitive comparisons of conventional systems are time consuming, processing intensive, and possibly inaccurate.

Moreover, in a variety of practical applications the data elements comprise independent attributes that effect dependent attributes. Conventional systems are not capable of distinguishing independent attributes from dependent attributes. Conventional systems, if at all, merely determine similarities based on matching dependent attributes alone, even though the underlying independent attributes causing these dependent attributes may be greatly different. For example, conventional systems may incorrectly determine that two hospitals are similar based on a similarity in the dependent attribute of worked hours per unit, even though the underlying independent variables that result in the worked hours per unit are entirely different, thereby causing a false similarity. In addition, the conventional methods do not lend themselves to post-processing verification and quality analysis.

In addition, typically, these precise data processing and comparison steps cannot be effectively performed manually. Even if it were possible to perform these processes manually, the manual processes would result the same errors and inaccuracies of the conventional systems described above, because manual processes also rely on mere comparison of data, whose faults are outlined above.

Accordingly, there is a need for an advanced systems that addresses the above technical problems in existing systems. The data structure clustering based on variation in data attribute performance of the present invention ameliorates the foregoing deficiencies of conventional database technology, and also provides several advantages and improvements. The technology, features, and functions of the novel comprehensive data transformation system of the present invention will be described in detail below.

FIG. 1 illustrates a comprehensive data transformation system environment 100, in accordance with one embodiment of the present invention, configured for data structure clustering based on variation in data attribute performance. As illustrated in FIG. 1, the data transformation system 106 is operatively coupled, via a network 101 to one or more database systems (108 a, 108 b), the user system/device 104, and to the third party system 160. In this way, the data transformation system 106 can send information to, and receive information from the one or more database systems (108 a, 108 b), the user system 104 and the third party system 160 to analyze and modify, in real-time, data structures and their interdependencies across a plurality of database systems (108 a, 108 b). FIG. 1 illustrates only one example of an embodiment of the comprehensive data transformation system environment 100, and it will be appreciated that in other embodiments one or more of the systems, devices, or servers may be combined into a single system, device, or server, or be made up of multiple systems, devices, or servers.

In some embodiments, the data associated with the data structures of the databases, may be generated by, provided by, accessed by and/or operated upon by the data transformation system 106, by the one or more database systems (108 a, 108 b), the user device 104 and/or other external or third party systems 160. For example, the system 106 may establish operative communication channels with the one or more database systems (108 a, 108 b), via the network 101. The system 106 may construct, or cause the first database system 108 a to construct, entity data structures 210 having a plurality of functional performance parameters 212 and a plurality of attributes 214, and/ the like (e.g., in the form of a class type extensible program-code-template, other object oriented data structures, linked lists, arrays, stacks, etc.), at the first database system 108 a. The system 106 may construct, or cause the second database system 108 b to construct, entity discrete attribute structures 230, peer data clusters 360 and/or the like, at the second database system 108 b. As described previously, the user 102 may refer to employees, technical subject matter experts, operators and other personnel associated with the entity or affiliates of the entity.

The databases comprising the plurality of entity data structures are typically stored in the one or more database systems (108 a, 108 b). In some embodiments the records (information associated with the data structures, attributes, etc.) from the database systems may be retrieved or accessed based on satisfying requisite authentication/authorization requirements. However, it is contemplated that some or all of the records may be stored in other memory locations/devices, for example, memory device 140, the user device 104, technology resources 150 and the like.

In some embodiments, each of the database systems (108 a, 108 b) may comprise a database control system, which is configured to receive submitted queries (e.g., retrieval requests, data storage instructions, etc. from the system 106) and manage run time access to the database. In the case of user-submitted queries, the conversion of user-submitted queries may be achieved through a query processor, which may translate the queries and/or commands inputted by the user into low level instructions which may then be executed by the runtime database manager. In this way, the database systems (108 a, 108 b) are able to provide a layer of abstraction through which the user may use identifiable commands to execute the addition, deletion, modification, querying, and retrieval functions of the database. The database control system may further serve the function of maintaining the structure and fidelity of the data by the use of error checking and/or correction.

In some embodiments, each of the database systems (108 a, 108 b) may further comprise a database engine which controls, secures and provides access to the data. The database engine may be responsible for authorizing and/or authenticating users and restricting some functions of the database depending on the user class. For instance, an administrator of the entity's systems may be provided with the least restrictive rule set, which may allow the administrator to freely add, remove, edit, and query the data within the database. On the other hand, a client of the entity may be provided only with access to the query functions of the database, while a member of the public may be precluded from utilizing some or any of the functions of the database.

The database systems (108 a, 108 b) may further comprise a report generation utility which extracts information from the databases and presents it to the user in a number of different formats. The user 102 may be able to select specific records for viewing in a desired format, such as graphs, charts, tables, formatted text, and the like. As the system allows for increasingly complex data mapping and relationships, the report generation utility is also able to display the complex data in a way that is most relevant and comprehensible to the user.

In some embodiments, in application of the invention in hospital applications, the database systems (108 a, 108 b) comprise thousands of data points about hundreds of hospitals that describe structural attributes at the facility and department levels, as well as the processes and tools used in administration and delivery of care. Having so many features about each hospital and department requires a statistical method to identify those features that best explain variation in performance. Any data point about a hospital or department, an operational process within a hospital, or the descriptors of the underlying patient population are referred to as “attributes” or “features”. Typically, all of these attributes describe something about a hospital that might impact or explain variation in certain measures of hospital performance (“functional performance parameter”). The present invention determines the combination of these attributes that explains the most variation in functional performance parameters (e.g., labor productivity), for a given department across all hospitals. Furthermore, the present invention determines the relative importance of each of those attributes—specifically the magnitude and direction of each attribute's effect on a particular functional performance parameters, controlling for all other functional performance parameters/features.

The network 101 may be a global area network (GAN), such as the Internet, a wide area network (WAN), a local area network (LAN), near field communication network, audio/radio communication network, ultra-high frequency wireless communication network, or any other type of network or combination of networks. The network 101 may provide for wireline, wireless, or a combination wireline and wireless communication between devices on the network 101.

In some embodiments, the user 102 is an individual associated with the entity. In some embodiments, the user 102 may access the data transformation system 106 through an interface comprising a webpage or a user technology application 122. Hereinafter, “user technology application” is used to refer to an application on the user system 104 of a user, a widget, a webpage accessed through a browser, and the like. In some embodiments the user technology application 122 is a system application stored on the user system 104. In some embodiments the user technology application may refer to a third party application or a user application stored on a cloud used to access the resource processing system through a network. In some embodiments, at least a portion of the user technology application 122 is stored on the memory device 140 of the data transformation system 106. The user 102 may subsequently navigate through the interface, retrieve one or more data structure records, provide confirmation, or review presented information using a user system 104.

FIG. 1 also illustrates the user system 104. The user system 104 generally comprises a communication device 110, a display device 112, a processing device 114, and a memory device 116. The user system 104 is a computing system that allows a user 102 to interact with the data transformation system 106 to request information, provide instructions, view results, etc. The processing device 114 is operatively coupled to the communication device 110, the display device 112, and the memory device 116. The processing device 114 uses the communication device 110 to communicate with the network 101 and other devices on the network 101, such as, but not limited to the third party system 160 and the data transformation system 106. As such, the communication device 110 generally comprises a modem, server, or other device for communicating with other systems/devices on the network 101. In some embodiments the network 101 comprises a network of distributed servers.

The user system 104 comprises computer-readable instructions 120 stored in the memory device 116/data storage, which in one embodiment includes the computer-readable instructions 120 of the user technology application 122. In this way, a user 102 may remotely communicate with the data transformation system 106, view retrieved data and visual displays, and/or modify, authorize, or monitor the implementation of data clustering activities using the user system 104 and the database systems (108 a, 108 b). The user system 104 may be, for example, a desktop personal computer, a mobile system, such as a cellular phone, smart phone, personal data assistant (PDA), laptop, or the like. Although only a single user system 104 is depicted in FIG. 1, the system environment 100 may contain numerous user systems 104.

As further illustrated in FIG. 1, the data transformation system 106 generally comprises a communication device 136, a processing device 138, and a memory device 140. As used herein, the term “processing device” generally includes circuitry used for implementing the communication and/or logic functions of the particular system. For example, a processing device may include a digital signal processor device, a microprocessor device, and various analog-to-digital converters, digital-to-analog converters, and other support circuits and/or combinations of the foregoing. Control and signal processing functions of the system are allocated between these processing devices according to their respective capabilities. The processing device may include functionality to operate one or more software programs or one or more modules, based on computer-readable instructions thereof, which may be stored in a memory device.

The processing device 138 is operatively coupled to the communication device 136 and the memory device 140. The processing device 138 uses the communication device 136 to communicate with the network 101 and other devices on the network 101, such as, but not limited to the one or more database systems (108 a, 108 b), the third party system 160 and the user system 104. As such, the communication device 136 generally comprises a modem, server, or other device for communicating with other devices on the network 101.

As further illustrated in FIG. 1, the data transformation system 106 comprises computer-readable instructions 142 stored in the memory device 140, which in one embodiment includes the computer-readable instructions 142 of a processing application 144 configured for data structure clustering based on variation in data attribute performance (described with respect to FIGS. 2-4 below).

As further illustrated by FIG. 1, the system environment 100 further comprises a one or more database systems (108 a, 108 b). The system environment 100 may further comprise technology resources such as system hardware, technology devices and applications, operating systems, servers, technology applications, internal networks, storage/databases, user interfaces, authentication operations, middleware, program products, external networks, hosting/facilities, business/ technology processes, and other technology resources or technology assets associated with the entity, not illustrated herein.

As discussed, the present invention is structured for data structure clustering based on variation in data attribute performance. Although the data structure clustering of the present invention finds many technical/practical applications in a variety of fields, the features and functions of the present invention are described herein using examples of implementation in the context of hospital type entities. It should be understood that these examples are provided for illustrative purposes only, and are not intended to limit the scope of the present invention. As discussed, the present invention is structured to link a sub-set of data structures out of a global set of data structures in a vector space to form a peer group (“peer data cluster”) based on identifying stimulus type attributes (independent attributes) that are structured to produce a functional performance parameter (dependent attributes) of the associated data structure. In the non-limiting context of hospitals, the independent feature selection, data clustering, and an extensive database of hospital characteristics of the present invention allows for identification of independent hospital attributes that explain variation in a functional performance parameter (performance metric) of interest, and to find peer hospitals that are similar in ways that matter to that functional performance parameter.

In some embodiments described herein, the present invention provides a system and process for choosing criteria for selecting peers, and adds consistency and transparency to the selection of peer group themselves (e.g., by using elastic net or another feature selection technique), in combination with k-nearest neighbors data clustering. This ensures that entities (e.g., hospitals or hospital departments) are comparing themselves to peers that are similarly situated in ways that matter to a particular functional performance parameter (performance metric). It further mitigates inherent errors described previously, and potential bias (unintentional or otherwise) that can creep into the process of choosing peers using conventional comparison methods and systems.

In the context of implementation of the present invention in hospital applications, as described, any data point about a hospital or department, an operational process within a hospital, or the descriptors of the underlying patient population may be referred to as “attributes” or “features”. Typically, all of these attributes describe something about a hospital that might impact or explain variation in certain measures of hospital performance (“functional performance parameter”). The present invention determines the combination of these attributes that explains the most variation in functional performance parameters (e.g., labor productivity), for a given department across all hospitals. Furthermore, the present invention determines the relative importance of each of those attributes—specifically the magnitude and direction of each attribute's effect on a particular functional performance parameters, controlling for all other functional performance parameters/features. These features and function of the present invention will now be described in detail with respect to FIGS. 2-4.

FIG. 2 illustrates a high level schematic representation 200 of data transformation data structures, in accordance with some embodiments of the invention. FIG. 3A illustrates a high level schematic representation 300A of data structure clustering, in accordance with some embodiments of the invention. FIG. 3B illustrates a high level schematic graphical representation 300B of data structure clustering of FIG. 3A, in accordance with some embodiments of the invention. FIG. 4 illustrates a high level process flow 400 for data structure clustering based on variation in data attribute performance, in accordance with some embodiments of the invention.

Specifically, FIGS. 2 and 3A-3B depict a line and symbol diagram representations of some of the data structures that may be constructed by the system and or that may exist within the multidimensional databases, in accordance with some embodiments of the present invention. FIGS. 2 and 3A-3B illustrate non-limiting examples of the data transformations performed by the invention. FIG. 4 outlines the algorithm process steps for performing the data transformations depicted in FIGS. 2 and 3A-3B. Typically, the process steps described herein are performed by the processing device 138 of the data transformation system 106, based on executing computer readable instructions/code 142 of the processing application 144, in some embodiments of the invention. The “system” as used herein may refer to the data transformation system 106.

Now referring FIG. 4, in conjunction with the schematic representations illustrated in FIG. 2, the system 106 may retrieve a retrieve a plurality of entity data structures 210 associated with a plurality of entities 205, e.g., from database systems (108 a, 108 b), at block 402 of process flow 400. Each entity data structure (210 a-210 m) is typically associated with a particular entity (205 a-205 m) (e.g., hospital or hospital department) and comprises operational process data within the entity, the descriptors of the underlying factors, and/or other data associated with the entity. Specifically, each entity data structure (210 a-210 m) may comprise a plurality of (or at least one of) functional performance parameters (212 a-212 m) and a plurality of (or at least one of) attributes (214 a-214 m), as illustrated by FIG. 2. Typically, the plurality of attributes (214 a-214 m) describe features, functions, or other parameters associated with the corresponding entity (e.g., urban geographic location of the hospital, location of the department in an acute care hospital, location of the department in a teaching hospital, patient volume, patient characteristics, etc.), while the functional performance parameters (212 a-212 m) describe performance metrics of the entity (e.g., worked hours per unit, relative department performance, patient discharge time, etc.). In some embodiments, each of the plurality of entities is a hospital and/or a hospital department, wherein the first functional performance parameter is associated with hospital performance, and wherein the plurality of attributes are associated with processes and/or patients associated with the hospital.

Next, at block 404, in order to construct a peer data cluster or a peer group that is structured to link the entity data structures of the plurality of entity data structures 210 that are similar, or whose corresponding entities are peers with respect to a first functional performance parameter (of the plurality of functional performance parameters 212 a) in a way that explains the incidence/prevalence/magnitudes of the first functional performance parameter, i.e., the stimuli/independent variables underlying the first functional performance parameter, the system 106 performs a first transformation 220 (illustrated by FIG. 2). Here, the system may first identify at least one independent attribute (234 a-234 m) (or one or more attributes) of the plurality of attributes (214 a-214 m) that is structured to cause, modify, stimulate, or otherwise affects the first functional performance parameter, for each entity data structure (210 a-210 m) of the plurality of entity data structures 210. Next, the system 106 may determine and correlate weight parameters (236 a-236 m) (e.g., coefficients) for each of the at least one independent attributes (234 a-234 m).

Subsequently, at block 406, for each entity data structure (210 a-210 m), the system may construct an entity discrete attribute structure (230 a-230 m) associated with an n-dimensional vector space comprising (i) the independent attributes (234 a-234 m) and the corresponding (ii) weight parameters (236 a-236 m). Typically, the independent attributes (234 a-234 m) are each associated with a vector dimension of the n-dimensional vector space. For instance, if the system identifies 26 independent attributes (234 a-234 m), the n-dimensional vector space has 26 vector dimensions, with “n” being equal to 26. The corresponding weight parameter (236 a-236 m) of the independent attribute (234 a-234 m) drives or triggers or provides a magnitude to the independent attribute in its respective vector direction. Typically, the system constructs the entity discrete attribute structure (230 a-230 m) based on linking, correlating or mathematically assembling (i) the independent attributes (234 a-234 m) and the corresponding (ii) weight parameters (236 a-236 m).

In some embodiments, the system utilizes a linear or logistic regression model for performing the independent attribute selection, weight/coefficient determination, and entity discrete attribute structure construction. Here, the entity discrete attribute structure may take the form of a quadratic function. In particular, in some embodiments, the system employs an elastic net implementation using the Python programming language. The system configures the elastic net implementation such that it explains the most variation in first functional performance parameter. Moreover, the underlying implementation performed by the system employs ordinary least squares regression, with two added penalty terms that balance between minimizing the number of independent attributes selected and the size of the weight parameters (e.g., coefficients) of those attributes.

Here, the system may first construct a linear regression model, as depicted below, with “p” being the number of attributes:

ŷ={circumflex over (β)} ₀ +x ₁{circumflex over (β)}₁ + . . . +x _(p){circumflex over (β)}_(p)

or, equivalently, in matrix notation, the foregoing function may be represented as:

ŷ=X{circumflex over (β)}

Specifically, the system may determine {circumflex over (β)} using the elastic net method as follows:

{circumflex over (β)}≡argmin(∥y−Xβ∥²+λ₁∥β∥₁+λ₂∥β∥²)

Here, the system typically selects and/or optimizes penalty terms λ₁ and λ₂ through multiple iterations of cross-validation to find the parameters that balance simplicity and explanatory power while avoiding over-fitting, e.g., based on employing an ElasticNetCV function of the Python programming language.

In some embodiments, the system stratifies the construction of the entity discrete attribute structures by department, volume metric, and/or performance metric such that, for example, (i) entity discrete attribute structures 230 based on the first transformation 220 explain the variation in the first functional performance parameter (e.g., worked hours per visit within emergency departments) across all entities (e.g., hospitals), while (ii) another second transformation 222 and the associated entity discrete attribute structures 240 explains the variation in a second functional performance parameter (e.g., worked hours per patient discharge within pharmacies) across all entities (e.g., hospitals). The second transformation 222 and the associated entity discrete attribute structures 240 are constructed in a similar manner to the first transformation 220 and the entity discrete attribute structures 230 above. Moreover, the system may perform other transformations for other functional performance parameters, in a similar manner. In some instances, in the context of hospital implementations, department volume may be treated as an interval variable, while some other hospital attributes may be treated as nominal (dummy) variables.

The entity discrete attribute structures are constructed such that, the resulting weight parameters/coefficients from the elastic net regression show the magnitude and direction of effect for each independent attribute. These entity discrete attribute structures are used as to construct peer clusters/groups using weighted k-nearest neighbors clustering, as will be described later on. In some embodiments, the constructed entity discrete attribute structures are reviewed by a user (e.g., a subject matter expert) as a quality check to ensure that the selected attributes could plausibly be related to department performance.

As an example, the weight parameters/coefficients 236 and the associated independent attributes 234 for a first functional performance parameter of worked hours per patient day within adult psychiatric units, across all entities 205 are provided in Table 1 below. The R² statistic for this particular example is 6. This is an example of one model stratum which can be used in conjunction with k-nearest neighbors clustering to form a meaningful hospital peer group.

Now referring block 408 of FIG. 4, in conjunction with the schematic representations illustrated in FIGS. 3A-3B, the system 106 receive a user input comprising a request for constructing a peer data cluster for a first entity data structure 210 a of entity 205 a of the plurality of entity data structures 210 for the first functional performance parameter, from a user device 104. In response, the system may determine a first entity discrete attribute structure 230 a of the plurality of entity discrete attribute structures 230 that is associated with the first entity data structure 210 a.

In response, as indicated by block 410, the system may construct the peer data cluster 360 for the first functional performance parameter of the first entity data structure 230 a. Here, the system constructs the peer data cluster 360 by k-nearest neighbors clustering, which typically structured to find a fixed number of entity data structures of entities (e.g., hospitals) that are most similar to first entity data structure 230 a of a particular entity 205 a (e.g., a specific hospital). Each constructed entity discrete attribute structure 230 a-230 m is positioned in an n-dimensional vector space 250, where each dimension represents an independent attribute that explains variation in first functional performance parameter (e.g., as determined by the elastic net feature-selection process, above). Note that the entities are not positioned according to their actual performance, but rather according to their independent attributes that affect the variation in performance. Although there are n-dimensions in the n-dimensional vector space 250 which cannot be represented easily in their entirety on paper, it is noted that FIG. 3A provides a schematic representation of the positioning of the constructed entity discrete attribute structures 230 a-230 m, while FIG. 3B provides its graphical representation in 3-dimensions, for ease of visualization purposes.

After spatially positioning the entity discrete attribute structures 230 a-230 m in accordance with their weight parameters along the independent attribute vectors, the system may then determine spatial distances between the first entity discrete attribute 230 a and each of the remaining plurality of the entity discrete attribute structures 230 b-230 m, in the n-dimensional vector space. Here, in some embodiments, the system may determine Euclidean spatial distances between the first entity discrete attribute 230 a and every other entity discrete attribute 230 b-230 m, e.g., using the calculation below:

$\sqrt{\sum\limits_{i = 1}^{n}\left( {q_{i} - p_{i}} \right)^{2}}$

Here, p=(p₁, p₂, . . . p_(n)) and q=(q₁, q₂, . . . q_(n)) are the Cartesian coordinates of each entity data structure's weight parameters of the independent attributes, which are may be determined by multiplying the weight parameters with a value of the respective independent attribute. In other words, the spatial or Euclidean distance is the distance in the n-dimensional vector space, where every impactful independent variable is represented as a single dimension, weighted by its effect on performance. This distance represents how dissimilar the two entity data structures are. A value of zero means they are the same while large distance suggests there are significant differences between the two entity data structures in ways that impact/affect performance parameters.

Next, the system may construct an ordered stack of the plurality of entity discrete attribute structures 230 by arranging the plurality of the entity discrete attribute structures 230 in an ascending order of the spatial distances. For example, for the example provided in FIG. 3, the ordered stack in ascending order of distances would comprise:

“[entity discrete attribute structure 230 b (with the smallest distance 310)], [entity discrete attribute structure 230(m-1) (with the next smallest distance 312)], [entity discrete attribute structure 230 m (with the next smallest distance 314)], [entity discrete attribute structure 230(m-2)] . . . ” and so on until the entity discrete attribute structure with the largest distance.

The system may then demarcate the ordered stack of the plurality of entity discrete attribute structures into (i) a peer stack comprising a first predetermined number of entity discrete attribute structures (e.g., 5, 25, 30, etc.) out of the plurality of entity discrete attribute structures selected in the ascending order of the spatial distances, and (ii) a non-peer stack comprising entity discrete attribute structures of the plurality of entity discrete attribute structures that are not in the peer stack. The peer stack consists of a fixed number of the closest structures. Continuing with the previous example, the system may determine the first predetermined number of entity discrete attribute structures to be 1 (or the user may input the required number of entity structures in the peer cluster), and demarcate the first peer stack as comprising the first structure in the stack, i.e., entity discrete attribute structure 230 b and the non-peer stack as comprising the remaining entity discrete attribute structures 230 c-230 m. Continuing with the previous example, the system may determine the first predetermined number of entity discrete attribute structures to be 2 (or the user may input the required number of entity structures in the peer cluster), and subsequently construct the first peer stack comprising the first two structures in the stack, i.e., entity discrete attribute structures 230 b and entity discrete attribute structure 230(m-1), and the non-peer stack as comprising the remaining entity discrete attribute structures 230 c-230(m-2) and 230 m. In some embodiments, the predetermined number of entity discrete attribute structures is 15, 20, 25, 30, and/or the like. Typically, the system determines the predetermined number of entity discrete attribute structures such that the peer stack is large enough to include as many similar structures as possible without being so large as to include structures that are dissimilar.

The system may then construct the peer data cluster 360 by linking the first entity discrete attribute structure 230 a with each of the entity discrete attribute structures in the peer stack, as indicated by block 410. Continuing with the example illustrated on FIG. 3A, for a first predetermined number of 1, the system may construct a peer data cluster 360A by linking the first entity data structure 210 a (i.e., the corresponding first entity discrete attribute structure 230 a) and the second entity data structure 210 b (i.e., the corresponding second entity discrete attribute structure 230 b). Similarly, for a first predetermined number of 2, the system may construct a peer data cluster 360B by linking the first entity data structure 210 a (i.e., the corresponding first entity discrete attribute structure 230 a) with both the second entity data structure 210 b (i.e., the corresponding second entity discrete attribute structure 230 b) and the (m-1)^(th) entity data structure 210(m-1) (i.e., the corresponding (m-1)^(th) entity discrete attribute structure 230(m-1)). It is noted that linking the entity data structures, as used herein, refers to, identifying the corresponding entity discrete attribute structures, and linking the corresponding entity discrete attribute structures.

Next, at block 412, the system may display, via a display device of the user device, a real-time interactive user interface comprising a representation of the peer data cluster for the first entity data structure. The representation of the peer data cluster may be one or more of the representations illustrated in FIGS. 3A-3B, and 6A-6C. Moreover, the system may determine a quality of the peer data cluster and present it on the real-time interactive user interface. The determination of the quality of the peer data cluster will be described below.

Upon constructing the peer data cluster, the system may determine various quality parameters associated with the peer data cluster, such as (i) an attribute quality indicating how much variation in the first functional performance parameter is explained by/caused by at least one independent attribute for each of the plurality of entity data structures, and (ii) a cluster quality indicating the degree of similarity within the peer data cluster, relative to all of the plurality of entity data structures. The system may further determine an overall quality by combining the (i) attribute quality and the (ii) cluster quality, as will be described below.

Attribute Quality

As alluded to above, attribute quality is a measure of how much variation in the first functional performance parameter is explained by/caused by the determined independent attributes. In some embodiments, the system may determine the attribute quality based on an R-squared function. The R-squared function represents the percent of variation in first functional performance parameter that is explained by the entity discrete attribute structure using the independent attributes chosen by elastic net. In some embodiments, there may be significant variation in the R-squared statistic across model strata. For some strata, the characteristics known about the entities (e.g., hospitals) in the database systems explain the majority of the variation in functional performance parameters while others may not explain much variation in performance.

A peer data cluster that is similar to the first entity data structure in ways that explain most of the variation in functional performance parameters is the most ideal. Alternatively, a peer data cluster that is similar but in ways that do not explain much variation in performance, is not much better a basis for comparison than a random group of entities (as would be the case when employing conventional systems). The R-squared function provides how much the independent attributes used in the peer data cluster formation matter to the associated functional performance parameter, when taken together.

FIG. 5 illustrates an example distribution of R-squared coefficients across a group of peer data clusters in which the functional performance parameter is worked hours per unit (WHpU). Typically, a predetermined first threshold, i.e., a minimum R-squared for a peer data cluster that explains more than half of the variation in its functional performance parameter is determined. If the system determines that the attribute quality is greater than or equal to the predetermined first threshold, the system allows the display of the user interface comprising a representation of the peer data cluster for the first entity data structure, at block 412. Alternatively, if the system determines that the attribute quality is less than the predetermined first threshold, the system may automatically and in real-time, block the display of the user interface comprising a representation of the peer data cluster for the first entity data structure, at block 412. Here, the system may also automatically and in real-time trigger (i) identification of another independent attribute of the plurality of attributes different from the at least one independent attribute by causing control to flow back to block 404, and/or (ii) a reconstruction of the plurality of entity discrete attribute structures by causing control to flow back to block 406.

Cluster Quality

As alluded to above, a cluster quality indicates the degree of similarity within the peer data cluster, relative to all of the plurality of entity data structures. In other words, the cluster quality is associated with a first degree of similarity (e.g., median distance) between the first entity data structure and the second entity data structure in the peer data cluster, relative to a second degree of similarity (e.g., median distance) between the first entity data structure and all of the plurality of entity data structures. The system typically determines the cluster quality as a distance ratio, i.e., a ratio of median distance between the first data structure (or another data structure at the center of the peer data cluster) and all of its peers, to the median distance from it to all the data structures. The median distances are calculated using the Euclidean distances determined above when the entity discrete attribute structures associated with the entity data structures are positioned in the n-dimensional vector space, in some embodiments. The distance ratio can be represented as:

${{Distance}\mspace{14mu} {Ratio}} = \frac{{Median}\mspace{14mu} {distance}\mspace{14mu} {to}\mspace{14mu} {data}\mspace{14mu} {structures}\mspace{14mu} {within}\mspace{14mu} {peer}\mspace{14mu} {data}\mspace{14mu} {cluster}}{{Median}\mspace{14mu} {distance}\mspace{14mu} {to}\mspace{14mu} {all}\mspace{14mu} {data}\mspace{14mu} {structures}}$

Typically, high quality peer data clusters are those where the median distance to entity peers within the group is small relative to the median distance to all entities. The above ratio ranges typically from zero to one. The closer to zero, the more similarity within the peer group and the less similarity to all other entity structures, i.e., the distance ratio being within a predetermined threshold range, the better the quality. If the system determines that the cluster quality. i.e., the distance ratio is within the predetermined threshold range, i.e., close enough to zero (e.g., within a range of 1-0.3, 0-0.5, etc.), the system allows the display of the user interface comprising a representation of the peer data cluster for the first entity data structure, at block 412.

The distance ratio closer to one, the less difference there is between the peer data cluster group and the rest, and the less quality the peer data cluster has. As an example, this can happen for two reasons: (i) for some outcomes and departments, there are no (or too few) other hospitals that are similar to the one being analyzed; and (ii) the members of the peer group are similar to the hospital being analyzed, but so are most other hospitals. In this regard, if the system determines that the cluster quality is outside the predetermined threshold range (e.g., does not match a range of 1-0.3, 0-0.5, etc.), the system may automatically and in real-time, block the display of the user interface comprising a representation of the peer data cluster for the first entity data structure, at block 412. Here, the system may also automatically and in real-time (i), reconstruct the peer data cluster such that the peer data cluster the first entity data structure is linked with all of the remaining entity data structures in the plurality of entity data structures (in the instances where all the entities are similar), or (ii) determine that the plurality of entity data structures are not compatible with the peer data cluster for the first functional performance parameter of the first entity data structure (in the instances where there are two few entities). In some embodiments, the system may further transmit a notification to user, via the user device, comprising an indication that (i) none of the plurality of entity data structures are compatible with the peer data cluster, or (ii) a number of the plurality of entity data structures is below a minimum threshold.

Overall Quality

The system may further determine an overall quality by combining the (i) attribute quality and the (ii) cluster quality, as shown below:

Overall Quality=Attribute quality×(1−Cluster Quality)

In other words,

Overall Quality=Rsquared×(1−DistanceRatio)

As a result, the overall quality statistic is close to one for the ideal combination of a high R-squared and small distance ratio, and approaches zero when either R-squared is very small, or distance ratio is very large, indicating a low quality peer data cluster. In response to determining that the overall quality does not match a predetermined threshold range, the system reconstruct the peer data cluster, e.g., by causing the control to flow to block 410.

Additionally, technical improvements provided by the present invention, which overcomes deficiencies of conventional systems, will be discussed below with respect to FIGS. 6A-6C. FIGS. 6A-6C illustrate, an illustrative examples 600A-600C depicting the improvements provided by the invention for various hospital entity applications. FIGS. 6A-6C illustrate the varying performance of a given hospital when evaluated against three distinct peer scenarios. Specifically, each of the plots 600A-600C compare, for a given entity (e.g., teaching hospital/department) and functional performance parameter, the distribution of performance: (i) across all other entities (hospitals), (ii) among other teaching hospitals as would be obtained by conventional methods, and (iii) within that particular hospital's peer data cluster by the data transformation system 106 of the present invention.

The differences between the system 106 of the present invention's data-driven feature selection, where the peers are similar in ways that matter, and a peer data cluster scenario consisting only of teaching hospitals as would be obtained by conventional systems are illustrated. The peer data cluster constructed by the system 106 of the present invention reflects a narrower range of performance because it is based on data-driven attribute selection, in all three cases 600A-600C.

In some cases, the range of performance across only teaching hospitals as would be obtained by conventional systems, is nearly the same as the range of performance across all hospitals, as illustrated by FIG. 6B. This suggests that teaching status is not at all helpful in explaining variation in that particular performance metric and department type. The peer data cluster constructed by the system 106 of the present invention ensures that peers are similar in ways that explain performance, and results in a smaller range of performance within the peer data cluster as indicated in plot 600B.

In all plots 600A-600C the hospital falls into different quartiles depending on how it selects its peer data cluster, for a functional performance parameter of worked hours per unit (WHpU), as indicated by Table 2 below:
